-1 = 1

I'll give a cookie to the person who finds out what is wrong with this. I know what it is, but it's fun to watch your brains twitch.

Sorry for bad formatting. Assume ,/(x) means square root of x.
I put it in words below if you can't read it.
-1 = -1

1/-1 = -1/1

,/(1/-1) = ,/(-1/1) 

,/(1) / ,/(-1) = ,/(-1) / ,/(1)

CROSS MULTIPLY

,/(-1) * ,/(-1) = ,/(1) * ,/(1)

-1 = 1



alternate formatting:
-1 = -1
1/-1 = -1/1
sqrt(1/-1) = sqrt(-1/1)
sqrt(1) / sqrt(-1) = sqrt(-1) / sqrt(1)
CROSS MULTIPLY
sqrt(-1)*sqrt(-1) = sqrt(1)*sqrt(1)
-1 = 1

Principal fucking roots. Jesus, we just had this thread like yesterday.

sqrt(-1) = ±i

i =\= -i but i^2 == (-i)^2

Don't call me gay, but I need some mary jay!
